Gabe Black ef650a5d24 libpayload: Check for completion more often in ehci_set_periodic_schedule.
This function was using mdelay in a loop to check for the completion of an USB
controller operation. Since we're busy waiting anyway, we might as well wait
only 1 us before checking again and potentially seeing the completion 999 us
earlier than we would otherwise.
